3D printing technique for guiding complicated cardiovascular surgery

The impressive guidance of three-dimensional (3D) printed model in surgery for a patient with right-sided aortic arch and Kommerell’s diverticulum, being presented in our former paper (1), leading to a sound outcome, has been highlighted as well as commented in the editorials which means a big honor for us. Kommerell’ diverticulum has been established a rare abnormity in some researches (2,3), even may be seen only once for some surgeons in their career, the medical management varies due to the rarity and complexity of this disease, including surgery, hybrid procedure, and conservative treatment with drugs. The surgical procedure of healing Kommerell’s diverticulum is somehow unfamiliar to surgeons, to some extend may be difficult, especially associated with a right-sided aortic arch. The way we introduced in our paper (1) way be a good experience to go by for cardiac surgeons.
